在本研究中，我们尝试了一种利用真菌青霉菌（Penicillium breviccompacactum WA 2315）合成纳米材料的环保工艺。这种真菌以前曾用于压实生产。利用种子培养上清液进行纳米银的生物合成。用真菌上清液处理后，水银离子被还原成银金属纳米颗粒。处理72 h后，得到的银纳米颗粒在23-105 nm范围内。采用紫外光谱（UV）、红外光谱（FTIR）、扫描电镜（SEM）、透射电镜（TEM）和x射线衍射（XRD）对纳米颗粒进行了表征。该真菌种子培养基上清液的使用为合理的纳米材料生物合成策略开辟了令人兴奋的可能性。2009爱思唯尔有限公司版权所有。
In the present study, an eco-friendly process for the synthesis of nanomaterials using a fungus, Penicillium brevicompactum WA 2315 has been attempted. The fungus has been previously utilized for compactin production. Supernatant of seed culture was used for the biosynthesis of silver nanoparticles. The aqueous silver ions were reduced to silver metal nanoparticles when treated with the fungal supernatant. After 72 h of treatment, silver nanoparticles obtained were in the range of 23-105 nm as obtained from TEM. The nanoparticles were characterized by UV, FTIR, SEM, TEM and XRD. The use of supernatant of the seed media of the said fungus opens up the exciting possibility of rational strategy of biosynthesis of nanomaterials. (C) 2009 Elsevier Ltd. All rights reserved.
